5 Tips to Help Protect Your Network from a DDoS Attack

While distributed denial of service (DDoS) attacks are nothing new, in the last year, we have seen larger, stealthier, more targeted and more sophisticated attacks than ever before, elevating the growing need for DDoS protection for companies of all sizes that conduct business online or are highly dependent on their online brand and reputation.
A denial-of-service (DoS) attack occurs when traffic is sent from one host to another computer with the intent of disrupting an online application or service. A DDoS attack occurs when multiple hosts (such as compromised PCs) are leveraged to carry out and amplify an attack. Attackers usually create the denial-of-service condition by either consuming server bandwidth or by impairing the server itself. Typical targets include Web servers, DNS servers, application servers, routers, firewalls, and Internet bandwidth. The following five tips can help you protect your online assets from a DDoS attack.

5 Tips for DDoS Protection:

  1. Centralize Data Gathering and Understand Trends: At the most basic level, successful DDoS protection involves knowing what to watch for, monitoring for unusual traffic patterns and activity, and staying abreast of what’s going on in the world to identify and validate potential/emerging attacks more rapidly to extract lessons learned into the appropriate incident response.
  2. Define a Clear Escalation Path: Systematic processes and methodology are essential for effective DDoS attack mitigation, such as having defined standard operating procedures and incident response teams in place. Also, it is important to prepare for downtime by understanding which systems are vital to your business, and developing and testing contingency plans for short-term (e.g., 1 hour), medium-term (e.g., 24 hours), and long-term (e.g., multiple-day) network or service outages.
  3. Use Layered Filtering: The goal of DDoS mitigation is to exclude only unwanted traffic while allowing legitimate traffic to enter the network with minimal delay. The most effective means to accomplish this is to use a multi-layered verification process.
  4. Build in Scalability and Flexibility: To make sure systems will function properly under attack conditions organizations must have a highly scalable, flexible infrastructure that has been tested in various scenarios to identify breaking points. It’s also important to use a distributed model to create and maintain redundancy for high-value applications and services.
  5. Address Application and Configuration Issues: DDoS attacks have evolved from brute force attacks at the network layer to more sophisticated, difficult-to-detect attacks at the application layer. Attackers can learn the acceptable threshold of activity for an individual application, and then sneak in as an unperceived increase in network traffic. In the overall context of the network, the increased traffic is not an issue, but if the targeted application has a low tolerance for high-volume traffic, the attack can take down the application.

WhatsApp is illegal, will soon banned in India : Government

WhatsApp could have accidentally entered into troubled waters here in India by enabling its end-to-end encryption for all. The new security feature by WhatsApp is not what is required by the Indian telecom rules and WhatsApp could face a ban, if the rules are not adhered to. But not yet.
In India, companies need to follow the country’s rules and adhere to specific types of encryption, which WhatsApp does not currently use. WhatsApp’s end-to-end encryption on its chat service means that WhatsApp or anyone else won’t be able to crack open its contents.  Only the sender and the recipient are able to read the encrypted data. WhatsApp uses a 256-bit key for encryption of all chat messages, which is only known to the sender and the recipient.
Why is it not possible for WhatsApp to help decrypt users’ messages? "No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us," WhatsApp founders Jan Koum and Brian Acton wrote on their blog. How…

3 Mega Acquisitions in last week affects the Internet Space of India

Qihoo 360 buys Opera in $1.2 Billion Opera Software intends to accept a $1.2 billion acquisition offer from a group of Chinese companies. The Chinese consortium includes Internet security company Qihoo 360, Internet firm Beijing Kunlun (which invested roughly$93 millioninto Grindr earlier in the year) and investment group Golden Brick and Yonglian. According to Opera, the $1.2 billion is a 56 percent premium over Opera's share price during the last 30 trading days. Despiteclaiming350 million users, the company's browser has struggled in the oversaturated Western market. China could be a profitable arena for Opera, in part because Google's Chrome browserdoes not come preinstalled on Android phones in China like it does elsewhere. In addition, doing business in China without local partners is nigh impossible, but Opera could leverage the networks of Kunlun and Qihoo 360 if the deal goes through.
